Introduction6:23
This is an introduction to the course. Here we will be learning about where you can use these skills, as well as the pattern and syllabus of the course.
What You Will Learn?3:56
Learn to add, subtract, and multiply two- to four-digit numbers quickly, including squaring and cubing two- and three-digit numbers, cube roots, percentages, long division, and square roots.

Divisibility Tests4:34
Multiplication Tables1:45
Learn to master multiplication tables up to 20 with a printable chart, practice daily to boost speed and prime factorization skills, and optionally memorize squares up to 30 squared.
Prime Factorization2:06
Learn prime factorization by writing numbers as the product of prime numbers, noting that primes have exactly two factors, 1 and itself, with practice on a digital worksheet.

Addition of Numbers2:58
Learn to add numbers quickly by splitting them into tens and units, practice two- and three-digit sums, and boost mental calculation speed with simple tips and tricks.
Subtraction of Numbers3:26
Multiplying Numbers by 112:34
Learn to multiply numbers by eleven using a simple method: keep the last digit, sum digits in pairs from the right, and carry as needed.
Squaring Numbers Ending with 52:22
Master the quick method to square numbers ending in five. The last two digits are always 25, and the remaining digits come from multiplying the non-five part by its successor.
Calculating Percentages2:45
Learn to calculate percentages quickly using tricks: multiply the numbers and divide by 100, and remember that x percent of y is the same as y percent of x.
Multiplying Numbers Close to Each Other4:23
BONUS: Dividing Numbers by 72:31
Master a fast trick for dividing numbers by seven. Memorize the sequence 1 4 2 8 5 7 and use remainders to reveal decimal digits.
Test Your Skills

Squaring Numbers Close to the Powers of 107:36
Learn to square numbers near powers of 10 using a base plus deviation method; derive the ending digits from deviation squared and the leading digits from the base plus deviation.
Multiplying Numbers Close to Powers of 105:23
Learn to multiply numbers near powers of ten by using the same base and deviations, compute deviation times deviation, add deviations to the base, and adjust digits for mental math.
Cubing Numbers that End with 13:16
Cubing Numbers Beginning with 13:20
Test Your Skills

Estimating Square-Roots and Cube-Roots5:30
Master rapid estimates of square roots and cube roots by using perfect squares, range narrowing, and a midpoint trick, with constant practice to improve speed and accuracy.
Squaring Numbers using non-10 bases7:39
Learn to square numbers using non-base-10 bases, starting with a quick base-50 method for two-digit squares and deviations, then apply a broader base method for larger numbers.
Using Algebraic Identities4:26
Everyone has their Own Way!4:15
Derivation of the Cubing Trick3:25

Requirements

Basic multiplication tables up to 15
Determination to spend at least an hour everyday practicing

Description

How much time and money do you spend every single day on Instagram, Netflix, or Hotstar?

Strike that, how many years did you spend studying physics, chemistry, or history in school? How often do you use that language in your day-to-day life?

What if I said that a mere 2-hour course could teach you to calculate faster than a calculator itself? Yes, I’m not kidding. 2 hours of theory and just 30 minutes of practice every day, and within a month you will take less time to calculate answers than it would take someone to enter those digits on a calculator.

So, what’s the catch? There isn’t one. This free course is designed to help people from all walks of life. If you’re a student who is unable to complete math exams because the calculations are too lengthy, this is for you. If you are an adult who needs to whip out his calculator for every little calculation when they go shopping, this course is for you.

Complete with instruction videos, assignments, and quizzes, this course is designed to take you from novice to expert in a matter of a few weeks. So, what are you waiting for? Jump in and let’s get started.

The course covers a variety of topics such as:

1. Addition of Numbers

2. Subtraction of Numbers

3. Multiplication of Numbers

4. Long Division

5. Calculating Percentages

6. Squaring of Numbers

7. Cubing of Numbers

8. Square Roots and Cube Roots

And all of this is do-able in under 4 seconds. If I can do it, and several hundreds of others can, then so can you.

Who this course is for:

Anyone who wants to excel in Math calculations!
Anyone who wants to impress people using their calculation skills!!
Anyone with a desire to learn and excel!
